2-octyl-4- quinoline

Primary halides are more reactive than secondary compounds quaternary salt formation does not occur with tertiary halides, elimination always occurring to give the hydriodide and an olefln, Also, the larger the alkyl group the slower is the reaction this is shown by the very slow reaction of dodecyl bromide with quinoline, and even butyl iodide is much slower to react than methyl iodide. The longer chain primary halides commonly undergo elimination rather than cause quaternization for example, n-octyl and cetyl iodides give only the hydriodides when heated with 9-aminoacridine. ... 

Having a spectroscopic polarity index Et = 0.426, furfural is of intermediate polarity, and on account of this property, furfural is infinitely miscible with other solvents of intermediate polarity, up to Et values of about 0.790, and down to Et values of about 0.099. At 25 °C, this infinite miscibility with furfural includes, in alphabetical order, acetic acid, acetone, benzene, butanol, butyric acid, chloroform, ethyl acetate, ethylene glycol, formic acid, octyl alcohol, oleic acid, propionic acid, pyridine, quinoline, and toluene. 

The scope of this extensively studied intermediate has included the preparation of a number of heterocyclic structures including quinolines, benzoxazoles, phenazines, phenoxazines and thiophenaazines (ref.94). Thus, 2-amino-4-t-octylphenol undenvent the Skraup reaction by heating with glycerol containing ferrous sulphate to afford 5-t-octyl-8-hydroxyquinoline. 5-t-Octylbenzoxazole resulted by reaction of 2-amino-4-t-octylphenol in formic acid with zinc and hydrochloric acid.
